Find the value of x and y of the equilateral triangle
Answer:
x = 12
y = 30
Step-by-step explanation:
We know:
All sides of equilateral triangle are equal:
= > 3 x + 8 = 4 x - 4
= > 8 + 4 = 4 x - 3 x
= > x = 12
Also, we know all angles of equilateral triangle is 60. And their sum is 180.
= > 2 y = 60
= > y = 30
Hence we get required answer!
Can someone please show me the steps to this problem. I know the answer is 64x but I need to learn the steps. There is a picture with the question.
Evaluate and find the answer.
X*4^8

4^5
Answer:
Here is the steps: (No link needed)
Step-by-step explanation:
First, cancel out 4^5 in both numerator and denominator. (Basically subtract 8-5 to get 3. The 3 is the third power below.)
So it looks like this:
4^3x
Calculate 4 to the power of 3 and get 64, then just add the x at the end.

Why do you sometimes finish the square (ex.[tex]x^{2} + 4x=1[/tex]) and sometimes you make one side zero(ex[tex]x^{2} -12x=-35[/tex])? How should I know the difference? Any help is appreciated! TIA
Answer:
Lets say there's a quadratic equation → ax² + bx = -c
Lets make one side zero which gives → ax² + bx + c = 0
From the above equation ,
if you can split b into 'p' & 'q' (some real numbers) such that p + q = b & pq = ac ; then the quadratic equation can be easily solved by using factorisation method. Here the easiest way to guess the values of 'p' & 'q' is to find out the prime factors of 'ac' and taking any two prime numbers in random , just check whether the sum of those two primes is equal to 'b' (excluding their signs).if you can't split b into 'p' & 'q' (some real numbers) such that p + q = b & pq = ac ; then try solving quadratic equation by completing the squares method.For example :- x² - 12x = -35.
Lets make one side zero → x² - 12x + 35 = 0 . Now, lets break -12x into two real numbers 'p' & 'q' such that p + q = -12x & pq = 35. Prime factors of 35 are 1 , 5 & 7. If we take 5 & 7 as 'p' & 'q' then p + q = 5 + 7 = 12. but as we need -12 , the values of 'p' & 'q' are -5 & -7.
⇒ [tex]x^2 -5x - 7x + 35 = 0[/tex]
⇒ [tex]x(x - 5) - 7(x - 5) = 0[/tex]
⇒ [tex](x - 5)(x - 7) = 0[/tex]
⇒ [tex]x = 5 \: or \: 7[/tex]
Lets take another example :- x² + 4x = 1.
Lets make one side zero → x² + 4x - 1 = 0 . Now , lets split +4x into into two real numbers 'p' & 'q' such that p + q = +4x & pq = -1 . Prime factors of 4 are 1 & 2 only. But there's no such combination of its primes such that their sum would be equal to 4. So, the quadratic equation can't be solved by factorisation method. Now, lets bring -1 to Right Hand Side & try solving by completing squares method.
⇒ [tex]x^2 + 2 \times x \times 2 + 2^2 = 1 + 2^2[/tex]
⇒ [tex](x + 2)^2 = 1 + 4 = 5[/tex]
⇒ [tex]x + 2 = +\sqrt{5} \: \: or \: -\sqrt{5}[/tex]
⇒ [tex]x = (\sqrt{5} - 2) \: or \: (-\sqrt{5} -2)[/tex]
Conclusion:
First try making one side zero and try to solve the equation by factorisation method. If it got factorised , then you are done and if it didn't get factorised , then solve it by completing squares method.
Answer:
I'm assuming we're asking about the difference between:
[tex]ax^2 + bx + c = 0[/tex]
and
[tex]ax^2 + bx = -c[/tex]
Let's preface this by stating the obvious: there's no actual difference. Both equations are equivalent.
Now, it has a lot to do with our goal. Sometimes our goal is to write an equation concisely (then the "no-zero" way uses less characters), and sometimes we're dealing with a quadratic function of
[tex]y = ax^2 + bx + c[/tex]
in the second case, we wouldn't write
[tex]y - c = ax^2 + bx[/tex]
because it'd be confusing. That means that when we're looking for y=0 points of a quadratic equation, the way to convey that goal is that we're looking for the point where [tex]ax^2 + bx + c = 0[/tex] - so we preserve the structure of the quadratic function.

Step-by-step explanation:
To find the are, you have to multiply the length x width
Let's solve that horizontal rectangle:
Length: 8
Width: 6
Area: 48ft
Now the trapezoid!! but we Must break it into two-pieces! so...
Length: 5
Width: 9
Area: 45ft
Finally the last shape that looks like a 90 degree triangle!!
Length: 5
Width: 5
Area: 25
I got the width by adding 9 + 6 then subtract by 20 which gives 5
Answer: 48ft + 45ft + 25ft = 118ft
Final Answer: 118ft

What happens if the red lines are NOT paralell. Which angle types are still congruent?
Step-by-step explanation:
The answer for the question is the first option, which is: Vertical. ... By definition, the vertical angles are those opposite angles that are formed by intersecting lines. Keeping this on mind, if the red lines shown in the figure above are not parallel, the vertical angles of each one them are still congruent.
Find the volume of th] cylinder. Round your answer to the nearest tenth if necessary. Use 3.14 for 1.
A can of juice has a radius of 3 inches and a height of 7 inches. What is the volume of the can?
The volume of the can is about
in?
Answer:197.8
The formula for a cylinder is 3.14*r^2*h but if you don't round to the nearest tenth the the answer is 197.82034.
Step-by-step explanation:Step one mutiply 3^2=9, Step two mutiply 3.14*
9=28.26, Step three mutiply 28.26*7=197.82.But if you round 197.82034 to the nearest tenth which is moving one decimal place to the right you'll will get 197.8.

A six-sided die is rolled eleven times. What is the probability that the die will show an even number exactly nine times?
Answer:
It is D
Step-by-step explanation:
6 x 11 = 66
3 x 9 = 27
The probability that the die will show an even number exactly nine times would be 23.438%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
A six-sided die is rolled eleven times.
Each roll has a 50 % chance to get even and odd.
The total possible outcomes for 6 die rolls = 64
The probability that the die will show an even number exactly nine times
= 15 /64
= 23.438%

milligrams of caffeine are in 3 ounces of the
same coffee?
Answer:
35 milligrams

To get from 12 ounces to 3 ounces, you need to divide by 4.
Do the same with 140 milligrams and you get 140/4=35 milligrams.
The graph shows the results of tossing two coins 20 times. The two sides of the coin show heads (H) and tails (T). Based on the results, what is the probability that both coins will show heads the next time the coins are tossed? 17 20 Two Coin Toss 8 CON Frequency ONWAY 3 20 HT TH HH IT 3 10
You forgot the picture
The probability that both coins will show heads the next time the coins are tossed is 3/20.
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
From the graph, Total number of outcomes= 7+6+4+3=20
Outcomes for both head =6
Then, P(HH)= 6/20
=3/10
Hence, probability that both coins will show heads is 3/20.
